Gargling is the act in which one bubbles a liquid in one’s mouth. It usually requires that the head be tilted back, allowing a mouthful of liquid to sit in the upper throat. The head can be tilted by extending either the neck or the back, depending on what is comfortable for the gargler. Air is then expelled from the lungs, causing the liquid to bubble and undulate throughout the throat and mouth region.
As gargling can be done repetitively with the same liquid for greater periods than a person’s lung capacity allows, one temporarily tilts the head forward to be able to breathe in again easily, as the liquid travels to the front of the mouth. Breathing in can be done through the mouth for people with nasal congestion; this requires a lesser amount of liquid so that it does not spill out when the mouth is opened for inhaling.
It is a common method of cleansing the throat, when gargling warm water and salt, if one has a sore throat due to upper-respiratory virus, infection or other cause
Swabbing the throat
The patient will be asked to tilt her/his head back and open her/his mouth as wide as possible. Press the tongue down with a tongue depressor and then examine the mouth and throat. The medication will then be rubbed over the back of the throat, around the tonsils, and over any red areas or sores .
